Etymology: Chiloglanis: Greek, cheilos = lip + Greek, glanis = a fish that can eat the bait without touching the hook; a cat fish (Ref. 45335).
Eponymy: George Latimer Bates (1863–1940) was an American farmer and amateur ornithologist. [...] (Ref. 128868), visit book page.

Environment: milieu / climate zone / Tiefenbereich / distribution range
Ökologie
; süßwasser; brackwasser benthopelagisch. Tropical; 5°N - 10°S
Africa: Niger basin (Ref. 57223, 81251), Oshun, Osse, Cross (Ref. 57223), headwaters of the Chad basin (Ref. 57223, 81251), and almost every river basin in Cameroon except the Ndian and Nyong; absent west of the Niger (Ref. 81251). Probably absent from the Congo basin where C. micropogon is found (see Ref. 87986).
Size / Gewicht / Alter
Geschlechtsreife: Lm ? range ? - ? cm
Max length : 4.0 cm SL Männchen/unbestimmt; (Ref. 57223)
Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 5 - 6; Afterflossenstacheln: 0; Wirbelzahl: 30 - 33. Diagnosis: labial disk/sucker rather large (Ref. 57223, 81251), round or longer than broad rather than transversely oval (Ref. 81251). Mandibular barbels reduced; mandibular teeth numbering at most 6+6, often 5+5, and occasionally 4+4 (Ref. 57223, 81251). Adipose fin high (Ref. 81251), rounded posteriorly, beginning slightly ahead of anal-fin origin (Ref. 57223, 81251). Caudal fin deeply forked; eyes rather large; very pronounced sexual dimorphism: males (even in premature stages) with enlarged caudal fin, in particular the upper lobe which also becomes more pointed or even filamentous; males also have a large and rounded humeral process (Ref. 57223, 81251).
Coloration: live specimens: diffuse dark vertical bars (that may even form a marbled pattern) delimiting better defined paler (yellowish or olivaceous) areas; dark vertical bars also present at bases of pectoral and caudal fin bases, but caudal-fin lobes pale yellow; finally, anal fin marked with dark spots, but these are less distinct than those in C. disneyi collected at the same locality (Ref. 57223, 81251).
Body shape (shape guide): fusiform / normal.
Oviparous (Ref. 205). Maximum total length 47 mm (Ref. 3202).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
